Our opinions are not our own, but in the power of sympathy. If a
person tells us a palpable falsehood, we not only dare not
contradict him, but we dare hardly disbelieve him to his face. A
lie boldly uttered has the effect of truth for the instant.
- William Hazlitt (1)

Dare to be true: nothing can need a lie;
A fault which needs it most, grows two thereby.
- George Herbert, Church Porch

Halfe the world knowes not how the other halfe lies.
- George Herbert, Jacula Prudentum

Shew me a lyer, and I'le shew thee a theefe.
[Show me a liar, and I'll show thee a thief.]
- George Herbert, Jacula Prudentum

Make the lie big, make it simple, keep saying it, and eventually
they will believe it.
- Adolph Hitler
